It is a case that has sex, violence, mafiosi, secret video and audio tapes and two defendants with a well-known name in Broward County.

The trial of Ralph and Tony Finno is scheduled to begin on Monday. The charges against them include racketeering, extortion, keeping a house of ill fame, loansharking and carrying a concealed weapon.

If convicted, Tony Finno faces nine to 12 years in prison, Ralph Finno five to seven years, Assistant Statewide Prosecutor Joel Lazarus said.

The Finnos also plotted to kill Broward Sheriff Nick Navarro, but no charges have been filed, prosecutors said.

Navarro is not likely to attend the trial, a spokesman said.

Ralph Finno, 54, was a Fort Lauderdale police officer for 27 years, rising to the rank of captain. He lost the race for sheriff against Navarro in 1988. Tony Finno, 47, was the chief electrical inspector for the city of Margate.

They were arrested in August after a six-month undercover Florida Department of Law Enforcement investigation. Police said the Finnos used threats of violence to take control of a sex club, ran a loansharking business and thought they were joining a Mafia crime family.

The Finnos` plan was to control graft in the county, with Ralph as sheriff protecting Tony, who wanted to become a mobster, authorities say. ``The word we got was Tony was the muscle, Ralph was the brains,`` Broward Sheriff`s Office Detective Frank Cornetta said in a pretrial statement.

FDLE informants John Red and Edward Wasco, described by FDLE as ``fringe guys`` in a Mafia family, videotaped 20 hours of meetings with the Finnos.

Jurors will be shown ``multiple hours of the tapes,`` Lazarus said.

``The tapes have an impact,`` said Fred Haddad, the attorney for Ralph Finno, but ``If you cut through the (expletive), they don`t really hurt us.``
